RS-485 Connector J5
The RS-485 connector (J5) is used to interface with the various SM supervisory modules.
Procedure
1. Remove the termination resistor assembly from RS-485 connector J5 located on the rear of the shelf.
See
Figure 28 .
2. Use cable P/N 552888 (ordered separately) (discard splices) to interface with SM-AC, SM-BAT, SM-RC,
or SM-IO supervisory modules. Connect this cable from the SM module to J5 located on the rear of the
shelf. See
Figure 28 for location.
3. If no SM module is connected to the system, ensure termination resistor assembly P/N 564702 is
installed onto connector J5 located on the rear of the shelf.
Mini Control Unit CAN Port Connector J4 (RJ-45)
The CAN port connector (J4) is used to connect a supporting device or system into the Mini Control Unit CAN
bus.
Procedure
1. Remove the termination resistor assembly from CAN port connector J4 located on the rear of the shelf.
See
Figure 28 .
2. Connect the device or system to CAN port connector J4 located on the rear of the shelf. See Figure 28
for location. Refer to Table 1 for CAN port connector J4 pin-outs. Ensure that the last device on the
controller’s CAN bus has a CAN termination resistor. Refer also to the external device’s or system’s
instruction manual.
NOTE!
Optional SM-Temp Module: The analog output of the SM-Temp Module may be connected to
an Mini Control Unit temperature port input. In lieu of connecting the analog output of the SM-TEMP
module to a Mini Control Unit temperature port input, the SM-TEMP module can simply be connected at
the end of the Mini Control Unit CAN bus. Refer to the above procedure and the SM-Temp Module
Instructions (UM547490) for details. Ensure the last SM-Temp Module (or if only one) has a CAN
termination strap as shown in the SM-Temp Module Instructions (UM547490).
3. If CAN port connector J4 is not used, ensure termination resistor assembly P/N 564703 is installed onto
connector J4 located on the rear of the shelf.
